OT: since we're speaking about the wrt3200acm, i have a question:

it seems that the four ethernet ports are connected to a single-chip ethernet switch, and appear as a single interface (called "lan" in my openwrt installation).

Is it possible, somehow, to "unbundle" them and make them appear as four different ethernet interfaces (like eth0...eth3) ?

I'm asking this because i have a vlan-capable switch and would like to have a separate network connection in each vlan, with the each network interface in its own zone.
